Retrograde orbit: the satellite (red) orbits in the direction opposite to the rotation of its primary (blue/black) Retrograde motion is motion in the direction opposite to the movement of something else and the contrary of direct or prograde motion. This motion can be the orbit of one body about another body or about some other point, or the rotation of a single body about its axis, or other phenomena such as precession or nutation of the axis.
Most of the research done on T. brucei's metabolism is on the microbe's lifecycle; however, T. brucei has shown to be a the most metabolically restrictive species of the Trypanosoma genus.(6) It is thought that horizontal gene transfer from bacteria to the Tritryp lineage is the cause of this versatility.
Calymmatobacterium, genus Calymmatobacterium-a genus of bacterial rods containing only the one species that causes granuloma inguinale. Francisella, genus Francisella-a genus of Gram-negative aerobic bacteria that occur as pathogens and parasite in many animals (including humans).gonococcus, Neisseria gonorrhoeae-the pus-producing bacterium that causes gonorrhea.l n, sing-rium (-rÉªÉm). 1.
